Hi Mustafa,
Query:” I add a detail grid under the grid, when I collapse and expand the
first grid, my data in the detail grid is lost”
Based on the information
provided, it appears that the screen recording captures the addition of data to
the detail grid but does not update the data in the data source. To prevent
data loss, we recommend using the update button to update the data source after
adding the data. This is the default behavior of the grid.
To assist you further, we have created a sample for your
reference. You can find the attached sample with this response.
Regards,
Prathap S
